The brothers had been living together on Norfolk Street in Cambridge. An uncle, Ruslan Tsarni of Montgomery Village, Md., told The Associated Press that the men lived together near Boston and have been in the United States for about a decade. They came from the Russian region near Chechnya, which has been plagued by an Islamic insurgency stemming from separatist wars.

An individual by the name of Dzhokhar Tsarnaev was a wrestler at the Cambridge Rindge and Latin School in Cambridge, Mass. He was named a Greater Boston League Winter All Star in 2011.

Cambridge Rindge and Latin School did not immediately respond to USA TODAY's phone calls. Many Boston-area schools were closed Friday.

In May of 2011, as a high school senior, Tsarnaev was awarded a $2,500 City Scholarship from the City of Cambridge to pursue higher education.

Before moving to the United States, he attended School No. 1 in Makhachkala, the capital of Dagestan, a predominantly Muslim republic in Russia's North Caucasus that has become an epicenter of the Islamic insurgency that spilled over from Chechnya.

His profile on the Russian social networking site Vkontakte says, he lists his languages as English, Russian and Nohchiyn Mott (a Chechen language). His world view is described as "Islam" and he says his personal goal is "career and money."

A "joke" posted on the profile page, translated from Russian, says: "There is a car... in the car sits a Dagestani, a Chechen and an Ingush. Question - who is driving? The answer: - The Police."

This is an old joke that has been told with a myriad of ethnic "passengers", meant to imply that if a certain ethnic person is in the car, the only reason would be because they had been arrested, says Andrea McCarren of WUSA-TV in Washington, D.C.

The father of the suspects in the Boston Marathon bombing claims that his son who is still on the loose is a smart and accomplished young man.

Anzor Tsarnaev spoke with The Associated Press by telephone from the Russian city of Makhachkala on Friday after police said one of his sons, Tamerlan, had been killed in a shootout and the other, Dzhokhar, was being intensely pursued.

"My son is a true angel," the elder Tsarnaev said. "Dzhokhar is a second-year medical student in the U.S. He is such an intelligent boy. We expected him to come on holidays here."

WUSA-TV posted that a search on VK.com, Russia's version of Facebook, resulted in a profile page believed to belong to Dzhokhar Tsarnaev. The page contains a photo of Tsarnaev updated in March and several posts, including YouTube videos. Tsarnaev posted a YouTube Video called "Caucasian Accents" to his page, but it's unclear whether he actually filmed it.

A "quote of the day" from one of his friends is posted on the page. It reads: "We want to beat up police officers on duty, burn their cars. walking in and blow up the house of politicians, journalists, bank managers and all those who work in banks. We want to break the bones of the Nazis' assault battalions." We want to undermine all the public service" (Revolutionary Group for the Propagation of Terror, Greece).

The page also shows a link the suspect claims to have graduated from in 2011: Cambridge Rindge and Latin School. The Cambridge News Weekly and CambridgeMa.gov indicate he won a City Scholarship from Cambridge and was an all-star wrestler in high school.

The profile also shows "last seen at 5:04 a.m., Boston." Could he have been looking at his page on Friday morning?
